Genus Hyperionyx Bowman 1973

Remarks

This genus is monotypic. It is readily distinguished by the relatively short pereopod 5, and in having pereonites 1–3 fused in both sexes. Virtually nothing is known regarding the biology, and there are not records of associations with gelatinous plankton.

It seems to be a rare circum­tropical genus. It has been recorded from the Mediterranean Sea ( Stephensen, 1924), the tropical Atlantic Ocean, off Florida ( Yang 1960), the South Atlantic Ocean, off South Africa ( Dick, 1970), the Gulf of Mexico ( Stuck et al. 1980), the tropical Pacific Ocean, near Fiji ( Hurley, 1960b) and the Indian Ocean (Bowman & McGuinness, 1982). I have also seen specimens from the tropical south­west Indian Ocean ( Galathea Stn. 230), the tropical South Pacific Ocean, near Panama (Dana Stn. 3960) and the Tasman Sea, off eastern Tasmania (SAMA).

Species: Hyperionyx macrodactylus ( Stephensen, 1924) .
